This study was examined the impact of acculturation stress and job satisfaction on the organizational commitment among dispatched hospital-workers in UAE. Data were collected with a convenience sample of 107 from March 1 to August 30, 2016. Analysis was conducted using t-test, ANOVA, Spearman rank-order correlation coefficient and Hierarchical regression analysis. The results of the study showed that first, the lower the acculturation stress, the higher the job satisfaction and organizational commitment, and the higher the job satisfaction, the higher the organizational commitment. Second, job satisfaction was significant to predict the level of organizational commitment among dispatched hospital-workers in UAE. Therefore, it is important not only to enhance the job satisfaction but also to reduce the acculturation stress before dispatch in order to improve the organizational commitment of dispatched hospital-workers, and various programs need to be developed for such education.

EQPS (Effluent Quality Prediction System, Dynamita, France) was applied to analyze the appropriateness of the design of a bioreactor in A sewage treatment plant. A sewage treatment plant was designed by setting the design concentration of the secondary clarifier effluent to total nitrogen and total phosphorus, 10 mg/L and 1.8 mg/L, respectively, in order to comply with the target water quality at the level of the hydrophilic water. The retention time of the 4-stage BNR reactor was 9.6 hours, which was 0.5 for the pre-anoxic tank, 1.0 for the anaerobic tank, 2.9 for the anoxic tank, and 5.2 hours for the aerobic tank. As a result of the modeling of the winter season, the retention time of the anaerobic tank was increased by 0.2 hours in order to satisfy the target water quality of the hydrophilic water level. The default coefficients of the one step nitrification denitrification model proposed by the software manufacturer were used to exclude distortion of the modeling results. Since the process modeling generally presents optimal conditions, the retention time of the 4-stage BNR should be increased to 9.8 hours considering the bioreactor margin. The accurate use of process modeling in the design stage of the sewage treatment plant is a way to ensure the stability of the treatment performance and efficiency after construction of the sewage treatment plant.

2012년 통계청 자료에 의하면 한국에 체류하는 외국인은 약 160만명이고, 그 중 방글라데시 노동자는 약 4.7%(한국고용정보원, EPS, 2012)라고 한다. 본 논문의 연구를 위하여 김해(100명), 마산(60명), 인천(40명)에 거주하고 있는 방글라데시 이주 노동자 약 200명에 대하여 설문조사를 실시하였다. 이 연구의 목적은 그들의 직업만족도와 삶의 만족도 사이에는 어떤 관련성이 있는지, 그들의 한국에서의 삶의 만족도를 높이기 위한 방안은 무엇인지에 대하여 알아보고자 하는 것이다. 연구 결과 직업 만족도의 ${\alpha}$ 값은 0.71, 삶의 만족도에 대한 ${\alpha}$ 값은 0.72 이었다. 직업만족도에 대한 설문은 Paul E. Spector(1985)가 고안한 것을 사용하였으며, 삶의 만족도에 대한 설문은 Thomas M. Krapu외 4인이 연구한 것을 사용하였다. 연구 결과 방글라데시 이주 노동자의 직업만족도와 삶의 만족도 사이에는 강한 관련성이 있으며, 그들이 느끼는 삶의 만족도는 매우 낮았다. 이를 높이기 위해서는 정부와 시민단체들의 적극적인 지원이 필요하다고 분석되었다.

This study was to analyse participant's satisfaction according to the visiting purpose and experiences on the exhibition service, and also to suggest guideline for new standard evaluation in the operating exhibition service. The implications are as follows; firstly, surrounding environment showed significantly for merchandising & information participant's, and also stay cost & tourism service showed up general visiting purpose participant's. Secondly, it was showed significantly a place for refreshment, fire equipments, and ventilation & heating/air conditioning on the exhibition service. Third, government & exhibition authorized person should provide best environment through satisfaction factors in the exhibition service.

The study aims to examine the determinants that affect satisfaction, revisit intention, and recommendation intention with foreign tourists who visited Korea despite the threat of COVID-19. This study employs the survey data collected by the Korea Tourism Organization from 8,135 foreign tourists who visited Korea in 2020. As the survey data contains a mixture of continuous and categorical variables, decision tree analysis can ensure analytical validity for the research. According to the analytical results, the determinants affecting satisfaction are the purpose of the visit and acceptance of self-quarantine during their stay. The factors influencing revisit intention are the purpose of the visit, frequency of the visit, and acceptance of self-quarantine during their stay. The determinants affecting recommendation intention are the purpose of the visit, length of stay, and gender. Based on the results of this analysis, this study not only explains the relationship between these determinants and tourism satisfaction, revisit intention, and recommendation intention, but also suggests implications for revitalizing tourism activities.

본 논문은 5G 네트워크의 주요 요구사항인 1ms 이내의 지연 시간을 만족하기 위해 새로운 SDN 기반 핸드오버 방식을 제안한다. UE로부터 이동성 정보와 BS의 상태 정보를 SDN 컨트롤러가 수집하고 가공된 데이터를 이용하여 다음 셀을 예측한다. 이 때, 셀 예측 시 계산량을 줄이기 위해 LP 문제 해결 기법을 적용한다. 또한, 예측된 셀에 대해 채널을 선 할당 하여 핸드오버 소요 시간을 줄이고 빠르고, 끊김 없는 서비스를 제공하게 된다. 실험을 통해 제안 방법은 이동 방향에 따라 신호 세기, 체류시간이 길고 셀의 부하가 적은 셀을 찾아냄을 알 수 있다.

This study examines degree of fairness migrant workers in Korea feel with their wages in comparison to those of their homeland and Korean workers who do the same job in Korea as theirs, and what factors affect the feelings. For the study, 742 migrant workers from China, Vietnam, Philippines, and Indonesia employed by manufacturing firms in Seoul and Gyenggi areas were surveyed. The results show that most migrant workers in Korea feel unfair about their wages, and the feeling of unfairness appears more strongly when comparing with the Korean workers than with their homeland workers. The effectiveness of variables affecting fairness also varies according to the object of comparison: in comparison to homeland workers, age, sex, monthly income before migration, money spent for employment, and satisfaction with working conditions are significant: in comparison to Korean workers, ethnicity, sex, legal status, satisfaction with working conditions are significant.
